SLIDESHOW: Zero in Ground Zero

The gravity of the impact of the magnitude 7.2 quake which struck Bohol is increasingly magnified in the towns near Ground Zero.

As rubble is cleared in town plazas, churches and homes in Bohol, the stark reality of what quake victims could face next haunts residents of the affected towns.

The national management disaster agency on Thursday said the death toll in Tuesday's quake is now at 158. At least 146 perished in Bohol, 11 in neighboring Cebu, and 1 in Siquijor.

In Loon, 42 people died, the largest number of fatalities in a single town recorded so far.

Ninety-two patients are staying in makeshift beds in open ground after the town's only hospital was destroyed by the quake. Sixty patients are at risk of dying if they're not given immediate medical attention.

Twenty-one people, 11 of them in Loon, remain missing. Five of the missing in Loon are believed to be buried under the town's 260-year-old Our Lady of Light Church that was reduced to rubble by the tremors.

A total of 671,967 families, or 3,406,227 individuals in 1,235 villages, were affected by the quake. At least 65,274 people are staying in 65 evacuation centers.

Around 18,265 houses were damaged in Cebu and Bohol, while 18 bridges were rendered impassable. At least 134 schools were also damaged.

Food, water, medicine and other medical supplies are also running out.
